One of the primary focuses of food microbiology is the study of foodborne pathogens – microorganisms that cause illness when consumed in contaminated food. You'll learn about the major foodborne pathogens, such as Salmonella, E. coli, Listeria, and Norovirus, their sources of contamination, and the mechanisms by which they cause disease. This knowledge is crucial for developing effective strategies to prevent and control foodborne illnesses.

The subject also covers methods for detecting and identifying microorganisms in food. You'll learn about traditional culture-based methods as well as more advanced techniques like PCR and ELISA. These methods are used to monitor food quality and safety, detect contamination, and identify the sources of outbreaks. Moreover, you’ll explore the various methods used to control or eliminate microorganisms in food. These include heat treatments like pasteurization and sterilization, irradiation, chemical preservatives, and modified atmosphere packaging. Understanding the principles behind these methods is essential for ensuring that food products are safe and wholesome.

3. Food Processing and Preservation

Food processing and preservation are central to ensuring that food remains safe, nutritious, and palatable from the time it's harvested or produced until it's consumed. This subject covers a wide range of techniques used to transform raw agricultural products into processed foods and to extend their shelf life. You'll learn about the principles behind these techniques and their effects on food quality and safety.

Food processing involves a variety of operations, including cleaning, sorting, grinding, mixing, heating, cooling, and packaging. Each of these operations can affect the physical, chemical, and sensory properties of food. You'll study the engineering principles behind these operations and how to optimize them to achieve desired product characteristics. For example, you might learn about the design and operation of heat exchangers used in pasteurization or the principles of fluid flow in mixing tanks.

Food preservation techniques aim to prevent or slow down the deterioration of food caused by microbial growth, enzymatic activity, and chemical reactions. Common preservation methods include heating (canning, pasteurization), cooling (refrigeration, freezing), drying, irradiation, and the addition of preservatives. You'll learn about the mechanisms by which these methods work and their effects on food quality. For instance, you might study how freezing affects the texture of fruits and vegetables or how different preservatives inhibit microbial growth.

Additionally, you’ll explore novel food processing and preservation technologies. These include techniques like high-pressure processing, pulsed electric fields, and modified atmosphere packaging. These technologies offer the potential to improve food quality, reduce energy consumption, and minimize the use of chemical preservatives. This knowledge is essential for developing innovative food products that meet consumer demands for safety, convenience, and nutritional value. The subject also addresses the regulatory aspects of food processing and preservation, including labeling requirements, safety standards, and quality control procedures.

4. Food Engineering

Food engineering applies engineering principles to the design, development, and operation of food processing equipment and systems. This subject is crucial for optimizing food production processes, ensuring food safety, and minimizing waste. You'll learn about the fundamental principles of heat transfer, mass transfer, fluid mechanics, and thermodynamics and how they apply to food processing operations.

Heat transfer is essential for many food processing operations, including heating, cooling, freezing, and drying.
